# convexity of bond

Bond Convexity - Measure of the "curvedness" or degree of curve the bond's price would take at different interest rates. According to bond convexity, the relationship between the price and the yield of a bond isn’t a straight one but rather a curved one, which means they are not directly proportional. Convexity can be negative if a bond contains an embedded call option. Just as before, the duration is used to calculate an initial approximation of the price change (ΔP) which is then further refined by the convexity part. As these calculations show, the actual percentage change in the bond price is –8.6%. Learn about the different types of government bonds and how to take a position. Terminology.

Therefore, if a bond has a duration of 5 years, it signifies that fo 1 r every 1% increase in the interest rate, the price of the bond will fall by 5% and vice-a-versa. On top of that, if we assume two bonds will provide the same duration and yield then the bond with the greater convexity will be less affected by interest rate change. Dollar Convexity • Think of bond prices, or bond portfolio values, as functions of interest rates. Also, bonds with greater convexity will have a higher price than bonds with a lower convexity, regardless of whether interest rates rise or fall. In the same way, we use the effective convexity to measure the change in price for a change in the benchmark yield curve … Enter the coupon, yield to maturity, maturity and par in order to calculate the Coupon Bond's Macaulay Duration, Modified Macaulay Duration and Convexity.
